Assuming this is actually for school:
There are many reasons school can act as a second home.
1) For the most part of 13+ years of our lives, we need to go to school to learn the basics tools that would allow us to have a better grasp and understanding of the world, as well as the knowledge on how to use technology, which has been evolving over the years.
2) As a class, students learn to work together with the teachers acting as "parents" (which promotes friendliness, workmanship, teamwork, cooperation, etc).
3) Like a family, there will be problems, such as arguments, fights, etc. at a school.
etc.
